号(1986年11月4日付)にさらに詳しく記載され
ている。(Prior Art) In recent years, thermal transfer systems have been developed for the purpose of printing images electrically produced by color video cameras. According to one developed method, the colors of an electrical image are first separated by color filters and each color image is converted into electrical signals. Cyan, magenta, and yellow electrical signals are then generated from these electrical signals and sent to the thermal transfer device. In a thermal transfer device, cyan, magenta and yellow dye-donor elements are placed in close proximity to a dye-receiver element for printing. These two elements are inserted between the thermal transfer head and the hot platen roller so that the linear thermal transfer head applies heat from the back side of the dye donor sheet. The linear thermal transfer head has a number of heating elements, each of which is continuously heated in response to cyan, magenta and yellow electrical signals. In this way, a color hard copy corresponding to the image on the screen is obtained. This process and an apparatus for carrying out this process are disclosed in US Pat.

細は英国特許2083726Aに記載されている。 Another method of obtaining prints using electrical signals as described above by thermal means is to use a laser instead of a thermal print head. In this method, the donor sheet contains a material that exhibits strong absorption at the wavelength of the laser. When the donor is irradiated,
This absorbing material converts light energy into thermal energy and transfers the adjacent dye by heating it to its vaporization temperature. The absorbing material may be present below the dye or mixed with the dye in the layer. The laser beam is modulated by electrical signals representing the shape and color of the original image, heating and transferring the dye to the receiver only where it is needed. Details of this process are described in UK patent 2083726A.

度のみならず、染料のレーザー吸収能と熱エネル
ギー変換能をも考慮しなくてはならない。 It is contemplated that various types of lasers may be used to thermally transfer the dye from the dye-donor sheet to the dye-receiving element. For example, ion gas lasers (e.g. argon, krypton); metal vapor lasers (e.g. copper, gold, cadmium); solid state lasers (e.g. ruby,
YAG); or diode laser (e.g. 750
Gallium arsenide (which emits in the infrared region of −870 nm) can be used. However, in practice, it is most effective to use diode lasers because of their small size, low cost, stability, reliability, uniformity, and ease of adjustment. In fact, before a laser can be used to heat the dye-donor element, it must be absorbed by the dye layer and converted into thermal energy by intramolecular energy conversion. Therefore, in order to create an efficient dye layer, it is necessary to consider not only the dye, its sublimability, and the strength of the image dye, but also the dye's laser absorption ability and thermal energy conversion ability.
